WebBohr’s Model of an Atom. Bohr’s model consists of a small nucleus (positively charged) surrounded by negative electrons moving around the nucleus in orbits. Bohr found that … WebBohr’s work was primarily based on the emission spectra of hydrogen. This is also referred to as the planetary model of the atom. It explained the inner workings of the hydrogen atom. Bohr was awarded the Nobel Prize in physics in 1922 for his work. Figure 1. Bohr’s atomic model hydrogen emission spectra.
Webelectrons. Another way of thinking about this model was that the atom was seen to be like a mini solar system where the electrons orbit the nucleus like planets orbiting around the sun. A simplified picture of this is This model is sometimes known as the planetary model of the atom. Figure 4.4: Rutherford's model of the atom.
